I noticed my ex-girlfriend rating our Uber driver 3/5 stars once we arrived at the airport. I asked her what was wrong with him. She said he was fine but it was just an average ride, nothing exceptional. And that she's only given out one 4/5 and zero 5/5's.
Not her fault. What choice do you have but to assign your own arbitrary meanings to each star, and how aren't those going to vary from person to person?
I agree it's frustrating that most sites leave it up to each individual user to decide what each star rating means.
On the other hand, I don't think it's really a problem as long as users are consistent. It doesn't matter how "harsh" they are as long as everyone has similar odds of getting a harsh reviewer.
I do tend to leave slightly below-average ratings because I like leaving room for truly exceptional products/experiences to get a higher rating.

I never looked at 5-star rating systems the same.
